About 2 months ago I switched my 91 Mercury Capri engine oil from 10w40 synth to 5w50 synth. and noticed a big improvement at the Capri's 90k. Finance's Rodeo has a nasty ticking sound at cold (common for the Isuzu v6), has a 140k on the odo, so I thought why not try the 5w50? bingo! qieted in right dowm. So a couple of weeks ago the Sporty was due. Put in 5w50 synth and I'm seeing a about 2 needle widths drop in coolant temp. not hearing the valve slap in the morning. got 42k odo. So far I'm liking it. So what's everybody else using? opinions?
